Strange microfossils

[Linda Hints <hints@xxxxx>]

Dear colleagues,

I have some strange-looking microfossils, likely single-chambered
foraminiferans, at my disposal. They were derived from insoluble residues of
Ordovician (Ashgillian) rocks of North Estonia. Their spherical, laterally
compressed test is seemingly composed of organic material. 
I have not found closely similar fossils in the literature, but indeed, my
experience concerning forams is rather poor. So, I would be pleased if
anyone common with such fossils could give me some advice on their
systematic position etc.
Three SEM photos and one from polished section can be reached at

Many thanks,
Olle Hints
